Percutaneous renal biopsies (PRBs) provide useful information in determining diagnosis, prognosis, and treatment plans for patients with renal disease. The procedure is considered relatively safe with low rates of complications, which include bleeding (rarely leading to death), extended duration of pain, arteriovenous fistula formation, and others. When patients experience postprocedural bleeding, renal arteriography and renal artery embolization (RAE) may be performed. Embolic agents used may include sterile compressed sponge (Gelfoam; Surgifoam, Ethicon, Somerville, NJ), polyvinyl alcohol (PVA) particles, microcoils, or n-butyl cyanoacrylate (nBCA). Success rates are high, and with careful selection of small vessels, kidney function can often be preserved.
